Metasaur is simply a random unnofficial name assigned to a group of arboreal volant tetrapods that lived in amber tree cavities often getting trapped when hibernating or when pregnant. This type of clean amber is difficult to find as it is not part of the amber mass on the trunk of the tree but from amber that has flooded a hollow in the tree. If you find difficulty seeing the fourth digit or the wingclaw then please look at our other macro and nano imagery or the micro ct slices or email us for fuller data.
The following image of Romeo's head, the small pterosaur in amber is provided with scale and to demonstrate the differences in imagery using different imaging techniques.

.

• micro-CT data on this volant


• To learn about an extroadinarily large similar volant creature


• photos of "scaly" volant head in the same piece of amber


• To view micro-CT data on scaly volant head


• large very well preserved anurognathid head in amber
nano-imaging is continually in progress and should you need updates please contact us
